|Former Scientific Name||
Immediately after biting their prey the adults secrete digestive enzymes into their prey. Diving beetles store air in a bubble held beneath their hardened wings. They use this oxygen during their underwater dives so they can hunt food and find mates. When prey numbers get too low, the beetles fly to a new water body and settle there. Adults lay their eggs in the water where tiny predatory larvae hatch out. The larvae spend their entire larval stage in the water before digging into the muddy banks and pupating.
